This 64GB SD Card is designed so that it fits into the SDXC of the MacBook Air 13" - so that it fits flush into the MacBook and doesn't poke out (preventing it getting caught on things).
"Introducing Transcend's JetDrive Lite storage expansion cards for the MacBook Air and MacBook Pro with Retina display. JetDrive Lite expansion cards are a quick and easy way to gain the additional space you need without adding any bulk to your MacBook." - Transcend Website (https://www.transcend-info.com/Products/No-637).
I used it to save my music on it, as its an easy way to upgrade the storage of a Macbook Air.
Bought for around $70, selling for $30 + postage which is either:
* Courier - $6 Non-Rural or $7 Rural - Tracking Details Provided (Will be NZ Post Courier).
* Snail Mail - $2 - I Don't Recommend this as no tracking is provided and is at the buyers risk.
No Pickups sorry.
The Transcend JetDrive will be reformatted before shipment.
Item is Second hand and is not in its original packaging (there was no manual that came with it - its plug n play)
This Transcend only fits the MACBOOKAIR 13" | Late 2010 - 2017
